Every summer when the outside temperature goes sky high I feel like my house is a sauna. I’m constantly turning the air conditioner temperature lower to make the temperature in my home bearable.
When I went to get something stored in my attic I almost passed out from the heat. What is going on with my house that it’s so hot?
There are a number of different variables that contribute to excessive heat in your living space. The biggest culprit is a lack of proper ventilation in your attic. The sun radiates through the roof causing increased temperatures. If your attic is properly ventilated it will allow that hot air to evacuate the space thus making your living space the desired temperature.
A properly ventilated attic requires two forms of ventilation. It requires intake ventilation (cooler air goes in) and exhaust ventilation (hot air goes out).
Many people are aware of the necessity for exhaust ventilation. Ridge vents, attic fans, static box vent and gable vent s are all forms on exhaust ventilation. But these exhaust vents are only efficient to allow the hot air out if there is a place for cooler air to come in and replace it.
Intake ventilation replenishes the hot air escaping from the exhaust vents. Vented vinyl or aluminum soffit, strip vents and rectangular vents are usually mounted underneath the overhang of the roof below the gutter.
On some houses where there is no overhang a new form of ventilation can be mounted to the roof deck prior to applying shingles. If the attic insulation is stopping the air flow then your ventilation system will not work properly.
Contact a professional roofing contractor to evaluate your ventilation.
